Astronomers discover massive radio galaxy 100 times larger than the Milky Way

Astronomers discover massive radio galaxy 100 times larger than the Milky Way.
Astronomers have discovered the largest radio galaxy ever, stretching at least 16 million light-years through space, new research shows.
The galaxy — named Alcyoneus after the son of Ouranos, the Greek primordial god of the sky — was discovered about 3 billion light-years from Earth by a "stroke of luck," according to a statement from Leiden University in the Netherlands.

Radio galaxies house supermassive black holes at their cores.
As matter falls into the black hole, it releases energy in the form of two radio jets from opposite sides from the galaxy's center, also known as an active galactic nucleus.
Using data from the Low-Frequency Array (LOFAR) network of radio telescopes located across Europe, researchers detected two massive plasma plumes emitted from a seemingly normal supermassive black hole at the center of the galaxy.
